Intellisence icons

Dear all,

I devellop my own language and I use the intellisence to help end users to write codes.

I use this instruction to fill items in the instellisence:

memberListItemHashtable["MySuggestion"] = new IntelliPromptMemberListItem("MySuggestion", (int)ActiproSoftware.Products.SyntaxEditor.IconResource.Keyword);
                                            

To set the item icon, I can use only an integer parameter to choose one from default list(ActiproSoftware.Products.SyntaxEditor.IconResource).

My question:

It can be possible to specify a custom icon and how do it.

Thx and regards,

Montasser
